How can we determine the equation of the line described ?. Put answer in the slope intercept form, if possible. Through ( -4, 2) perpendicular to x = - 8

#a^2 + b^2 = c^2#

Answer 1

#y=2#

#"the line with equation "x=-8#

#"is a vertical line parallel to the y-axis passing through"# #"all points with an x-coordinate of 8"#

#"A line perpendicular to it will be a horizontal line with"# #"with equation "y=c" where c is the value of the"# #"y-coordinate the line passes through"#

#"line passes through "(-4,2)#

#rArr"it's equation is "y=2# graph{(y-1000x-8000)(y-0.001x-2)=0 [-10, 10, -5, 5]}
